Overcalls
Updated 16 October 2026
Your side does not have to pass when the opponents open. An overcall names a suit of your own straight over their opening. It fights for the contract, takes room from the opponents and, if they end up declaring, points partner to the right lead. Because partner may well lead it, the quality of the suit counts for more than the points, and the two level asks for more than the one level.
What is an overcall?
An overcall is a bid in a suit after an opponent has opened the bidding. If the player on your right opens 1♣ and you bid 1♠, you have overcalled. Your bid has to be higher than theirs, so the level depends on where your suit ranks. Over 1♣, any of the other three suits can be bid at the one level. Over 1♠, every other suit has to go to the two level.
An overcall does three jobs at once. It can win the contract for your side, often a part score the opponents would otherwise have played. It uses up bidding space the opponents wanted for their own auction. And if they end up declaring, it tells partner which suit to lead.
At the one level you need 8 to 16 HCP and a good suit of five cards or more. That is fewer points than an opening bid, because you are showing a suit rather than promising to find a contract on your own. A hand of 17 or more is too strong for a simple overcall and starts with a different call, which the next lesson explains.
A good suit matters more than points
Partner will raise you with three cards and will lead your suit against their contract, so the suit has to deserve it. A good overcalling suit holds at least two of the top three honors, or three of the top five (A, K, Q, J and 10). Points in your other suits do not help partner's lead, and they do not save you when the opponents double you and your trumps break badly.
The third suit has only one of the top three honors, but the king, jack and 10 make three of the top five. The last two hold a single honor each. Overcall in them and partner's lead of your suit may hand declarer a trick. A hand with a suit like that usually passes, even with 11 or 12 points, unless its shape fits the double of the next lesson.
Higher overcalls and partner's raise
The two-level overcall
When your suit ranks below theirs, you have to bid it at the two level, and that asks for more. You are contracting for eight tricks instead of seven, and the opponents have more room to double you. A two-level overcall needs opening values, about 12 to 16 HCP, and a good suit, usually of six cards. Over 1♠, a hand with ♥AQJ1074 and an outside ace and king makes a sound 2♥. Give it ♥97543 instead and it should pass.
The 1NT overcall
A 1NT overcall shows a balanced hand of 15 to 18 HCP with a stopper in the opener's suit. A stopper is a holding that should win a trick in their suit when they lead it, such as the ace, KQ, or the king with two small cards. The range is a touch higher than a 1NT opening because opener has shown some of the missing points. Partner answers as if you had opened 1NT, and Stayman and transfers work just the same.
Raising partner's overcall
When partner overcalls, three cards in the suit make a fit, and a raise is the bid partner most wants to hear. Raise to the two level with three-card support and about 6 to 9 points. The raise takes more bidding room away from the opponents and confirms the lead, so do not hold back with a fair hand. If you have no support and a weak hand, pass. Partner may have overcalled on 8 points, and a new suit from you would only push your side higher.
Watch it in a deal
You are South. East opens, and your overcall finds a part score for your side.
East opens 1♣. You hold 13 points and ♠KQJ94, a strong five-card suit, so you overcall 1♠. West passes, and North has three spades and 7 points, enough to raise to 2♠. The raise shows 6 to 9 points, so game is out of reach and everyone passes.
What to take to the table
Before you overcall, look at the suit first and the points second. A good five-card suit is worth showing at the one level with as little as 8 points, while a ragged suit is better left unbid even with more. At the two level, ask for opening values as well. When partner overcalls and you have three-card support and a few points, raise.
